For each of the pixel unit groups (P1), the aperture region (A12) of each of the first pixel units (P0) and the shielding region (LS1) of the shielding layer at least partially overlap. The aperture region (A12) of at least one of the first pixel units (P0) comprises a first shield connection portion (SP1) at least partially overlapping with the shielding region (LS1) of the shielding layer (LS). The shielding layer (LS) is connected to at least one of the first power supply lines (VDD1) by means of the first shield connection portion (SP1).
